Chill a cocktail coupe in advance to ensure optimal temperature.

Prepare a twist of grapefruit zest for garnishing.

Combine Hayman's London Dry Gin, Strucchi Rosso Vermouth, freshly squeezed pink grapefruit juice, and a dash of Angostura Aromatic Bitters in a shaker.

Add ice to the shaker and shake vigorously until well chilled.

Fine strain the mixture into the pre-chilled coupe glass.

Express the grapefruit zest over the cocktail to release its oils, then use it as a garnish.
